Trait Implementations

impl Clone for Blake2b256

fn clone(&self) -> Blake2b256

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Blake2b256

fn default() -> Self

Returns the “default value” for a type.

impl FixedOutput for Blake2b256

fn finalize_into(self, out: &mut DigestOutput<Self>)

Consume value and write result into provided array.

fn finalize_fixed(self) -> GenericArray<u8, Self::OutputSize>

Retrieve result and consume the hasher instance.

impl FixedOutputReset for Blake2b256

fn finalize_into_reset(&mut self, out: &mut Output<Self>)

Write result into provided array and reset the hasher state.

fn finalize_fixed_reset(&mut self) -> GenericArray<u8, Self::OutputSize>

Retrieve result and reset the hasher state.

impl OutputSizeUser for Blake2b256

type OutputSize = <CoreWrapper<CtVariableCoreWrapper<Sha256VarCore, UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>>> as OutputSizeUser>::OutputSize

Size of the output in bytes.

fn output_size() -> usize

Return output size in bytes.

impl Reset for Blake2b256

fn reset(&mut self)

Reset state to its initial value.

impl Update for Blake2b256

fn update(&mut self, data: &[u8])

Update state using the provided data.

fn chain(self, data: impl AsRef<[u8]>) -> Self

Digest input data in a chained manner.

impl Write for Blake2b256

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write(&mut self, buf: &[u8]) -> Result<usize>

Write a buffer into this writer, returning how many bytes were written.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

Creates a “by reference” adapter for this instance of Write.
